**Hosted by Pure Storage** Please note at the Pure Storage office, all meetup attendees will be required to sign a generic NDA used for all office visitors to be able to attend the meetup. Doors are open from 17:30, talks will start 18:00, and we have 2 talks and panel discussion. **1\. Daniel Turecek \(Pure Storage\) \- What is new in Go 1\.26** In this lightning talk, we’ll tour what’s coming in **Go 1.26** (based on the current draft release notes) and why it matters for real-world services. We’ll cover runtime and performance wins like the default **Green Tea GC**, faster **cgo** calls, improved stack allocation, and new profiling options aimed at spotting goroutine leaks. We’ll also look at security and crypto upgrades including 64-bit heap address randomization, the new **`crypto/hpke`** package, and **post-quantum hybrid key exchange on by default in TLS**. Finally, we’ll touch on pragmatic developer-experience changes—from `new(expr)` and richer generics constraints to tooling updates like `go fix`, `pprof` flame graphs by default, and compatibility-oriented module defaults. **2\. Vilibald Wanca \- Nail the Basics \- S01E02** Good Go code starts with a simple, predictable layout. In this talk, we’ll cover the standard approach to structuring Go projects: keep things flat early on, map one package to one directory, and keep tests right next to the code they validate (like `user.go` and `user_test.go`). We’ll also look at common structural mistakes—such as over-engineering too soon or importing Java/Python-style layering that fights Go’s package model—and how to avoid them. Finally, you’ll leave with a handful of quick wins you can apply immediately: formatting and import automation with `gofmt`/`goimports`, stronger feedback loops with `golangci-lint`, and editor setups (VSCode Go extension or GoLand) that make the “Go way” feel effortless. **3\. Panel discussion with our speakers on AI tools and Go development** Join us for a panel discussion with our speakers on how AI tools are changing Go development in practice. We’ll compare real workflows for using assistants to design, code, test, refactor, and review Go services—what actually saves time, what introduces risk, and where humans still need to stay firmly in the loop. Expect practical tips on prompt patterns, maintaining code quality, avoiding “AI-shaped” over-engineering, and integrating AI into existing tooling like linters, editors, and CI. Bring your questions—we’ll keep it candid, concrete, and Go-focused.

We’ve got another portion of AI talks for you, so come to our second Prague Gen AI Meetup of the year. ## NEW VENUE (very important) **Pracovna & Laskafe** Vlkova 628/36, 130 00 Praha 3-Žižkov ## Venue Schedule * **18:30** Doors open * **18:45** Talks start * **20:45** Talks end * **21:00** Snacks and beer ## What’s On The Agenda * **Talks:** Again, no hype, just the stuff you want to know. * **Snacks and Beer:** Grab a bite and a brew while talking shop. * **Networking:** Meet other people in the field. No fluff, just good tech talk. ## Talks ### Šimon Podhajský (Head of AI @ Waypoint) **The Eval Flywheel: From "Works on My Laptop" to Systematic Quality** Most teams shipping GenAI products have no evaluation system. They have vibes, a few saved prompts, and hope. This talk doesn’t start with “build an eval suite”, it starts with **observability**: if you can’t see what’s happening in production, nothing else matters. From there, we build the **eval flywheel**, a practical pattern where production observability feeds error analysis, error analysis generates eval cases, and eval cases prevent recurrence. Your evaluation suite isn’t something you design upfront, it’s something that grows out of understanding your production failures. ### Ondřej Romancov (Engineering Lead @ Duvo.ai) **Building agents with agents** Duvo is building a platform for AI agents, and we’re running our engineering on agents too. Sharing practical tips and workflows we’ve found useful along the way. Let’s get down to the real talk.

In a world full of opinions, noise, and quick reactions, we often miss spaces for real dialogue — for slowing down, listening, and connecting with one another. This evening is an invitation to do exactly that. Join us for an open and friendly evening (in English & free of charge) dedicated to Automated Commonwealth (UBI - Universal Basic Income), can we use AI for people's welfare? Is it a basic income what we really need? We will brainstorm together in an Open Space–style format, where participants choose topics themselves, and what we want to discuss from this broad topic - questions to help you get inspired: Is it possible to achieve automated UBI? Is UBI what we need, or is it better social infrastructure? How do we start building such system? Afterwards, participants will form small groups to explore the questions and insights around the topics 18:00 – Doors open 18:15 – Introduction & topic selection 18:40 - We start discussions 19:40 - Closing session (sharing activities) 20:00 - Networking & Connect What to expect: A welcoming space for newcomers and regulars alike Be slightly pushed to socialise Open, participant-led small-group discussions on diverse perspectives No expertise required — everyone’s opinion matters! Safe, respectful, and judgment-free conversations More about sharing and reflecting than debating or convincing No pressure to speak — listening is just as valuable Not a lecture, not a debate club, and definitely not intimidating! Feel free to bring some snacks to share! Friendly dogs are welcome! If you are a regular that appreciate us and can help, or a newcomer who enjoyed the evening, and wants to help, we have recently set a patreon page where you can support us! https://www.patreon.com/cw/EarthSocietyDialogues

This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

Kevin Rhodus from Lucy Deep Park Northside is coming to talk to us about his extensive neighborhood Christmas light display that is open in November and December every year north of Dublin. 9 houses over 12 acres and over 120,000 individual controlled lights that sync to music which you can tune into on your radio! Quite impressive! https://ldplights.com/ We'll dive into the tech that runs the show -- should be a blast to hear about this very elaborate display! While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Dublin Library in the Meeting Room 2

Bring your work or your hobby, hang out, and code with us. Follow @buckeyecocoa for more information.

The Forge does have a full bar and kitchen. There is no cover charge but they do request all attendees to purchase a minimum of ~$20 per person. Soft drink refills are $1 each. Please support our hosts so we can continue to provide great events for the group! The Forge has a large library of games available for us to enjoy. Hosts and regulars will also provide numerous popular games but please bring any games you would like to teach and/or play. Doors open at 6, and we expect gaming to be rolling by around 630. Please promptly end your games and clear out the space at 10pm when the bar closes. We encourage socializing but do not permit disruptive behavior of any kind. Thank you for your continued commitment to providing a fun and welcoming space to veteran, newbie, and rookie gamers in the Columbus area. Parking can be challenging. There is a parking lot behind the neighboring Mexican restaurant that is free and easy to walk from but it's a bit hidden.

Meeting @ Improving's office in Downtown Columbus, near Cosi. Parking is paid, food & drink are free! This time we're hanging out after the long winter break. We are going to look at a group-member's project used to help learn the fundamentals of Go, and if time allows, we can take a look at how we like to build Go projects using AI.

Welcome to Casual Boardgames, where we enjoy classic tabletop games and social deduction games while bonding over good food, drinks, and great conversations. 
We started this group to meet new people and make new friends, and bonding over games in a relaxed atmosphere is a great way to do that. We currently meet near route 23 and Polaris Parkway, and this is close to areas like Powell, Lewis Center, Worthington, and parts of Westerville and Columbus. 
Feel free to bring your own games or play one of the many games our members bring. If you are inexperienced, we will help you learn. 
Here are just a few examples of the kind of games we play. 
Tabletop/board games: Splendor, Catan, Azul, Dominion, 7 Wonders… 
Social deduction games: Code Names, Chameleon, Werewords… 
IMPORTANT: 
1. While we love playing a variety of games and competing, we are not just about the games. We interact and talk while playing, and this leads to a lot of laughter and fun. If you just want to compete and focus solely on the game, then this is probably not the group you are looking for. 
2. Many people join groups like this and never (or rarely) show up after weeks or months. If you join and never really come, we will eventually remove you from the group as a courtesy to our members. Why? Because limiting group conversations (on the app) to regular members makes communication and planning much easier. Also, while it may be rare, it protects members from people who join because they are interested in following a person instead of having a real interest in our group. If you get removed, it is just because you haven’t come, and we follow this protocol as a courtesy to our regular game players.
